c# - 如何通过 C# 使用 Web 服务端点

Question

我想通过C#向以下端点发出get请求。

http://api.example.com/1/companies/ {id}

我正在查看 WCF Rest 入门工具包，想知道除了安装 Rest 入门工具包之外还有其他方法可以轻松发出获取请求。

请提出建议。谢谢，

这是一个将从 URL 执行 GET 并返回字符串的方法:

public static string GetResponse(string endPoint)
        {
            HttpWebRequest request = CreateWebRequest(endPoint);

            using (var response = (HttpWebResponse)request.GetResponse())
            {
                var responseValue = string.Empty;

                if (response.StatusCode != HttpStatusCode.OK)
                {
                    string message = String.Format("POST failed. Received HTTP {0}", response.StatusCode);
                    throw new ApplicationException(message);
                }

                // grab the response  
                using (var responseStream = response.GetResponseStream())
                {
                    using (var reader = new StreamReader(responseStream))
                    {
                        responseValue = reader.ReadToEnd();
                    }
                }

                return responseValue;
            }
        }

编辑:

private static HttpWebRequest CreateWebRequest(string endPoint)
        {
            var request = (HttpWebRequest)WebRequest.Create(endPoint);

            request.Method = "GET";
            request.ContentLength = 0;
            request.ContentType = "text/json";

            return request;
        }
